Organic Light Emitting Diode (OLED) technology was the star of the electronics trade shows this year. At this year’s Consumer Electronics Show in Las Vegas, the biggest product introduction was made by Sony, with an OLED display. The new 11 “Sony TV calLED XEL-1″. Sony HDTV is extremely thin (less than 1 / 10 “) and lightweight. At the FPD International Exhibition in Asia in November, Samsung introduced a 31″ OLED HDTV with 1080p resolution and contrast ratio of 1,000,000: 1.
Companies such as LG, Toshiba, Matsushita (Panasonic), are investing hundreds of millions of dollars, the development of this promising technology. Toshiba plans to sell a 30 “OLED display in 2009. Samsung said it would sell big-screen OLED devices in 2010.
Eastman-Kodak holds a number of patents in OLED technology. Manufacturers will probably be required to pay a license fee for all Kodak OLED televisions sold. Eastman-Kodak just introduced the OLED Material EK-GD403, which uses green dopant technology. Advanced technology is a stampede.
There’s a lot of money to be made. According to DisplaySearch, in 2007, the market for LCD TVs was estimated at 27.4 billion U.S. dollars, while the market for plasma TVs was estimated at 7.5 billion U.S. dollars. A competitive cost OLED TV, which was likely to get a significant share of this market. DisplaySearch estimates that the OLED market growth at over 17 billion dollars a year by 2015. According to iSuppli, the current market for OLED devices is more than half a bit ‘a billion dollars a year. Samsung currently has a 70% share of the market. But the cost and hassle of OLED technology have prevented it from being used in large equipment such as HDTV or computer monitor.
Easy HDTV wall-mountable
Most consumers say they want a wall-mountable HDTV. However, according to the NPD Group, a consumer and retail research firm Information Market (NPD.com), only 13 percent of current LCD TV owners and 25 percent of the owners of plasma televisions say that their set is mounted on the wall.
“Consumers are attracted to flat panel technology for their ability to wall mounting, but the difficulty of such a system, often leads them to explore alternatives such as plant or dealer is.” said Ross Rubin, director of industry analysis, The NPD Group. But with OLED, the task of assembling the hardware would be much easier, like hanging a picture on the wall. The hardware weighs a fraction of LCD or plasma.
OLED Performance
OLED is already used for some time in digital cameras, cell phones and other devices with relatively small panels, because they are very efficient, which is very important in portable devices.
A significant benefit of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. Because of this, they draw much less power. And because there is no backlight, an OLED display is much thinner than an LCD display.
And because there is no backlight, an OLED system has a wider viewing angle of a system of LEDs and an OLED display can be much thinner than an LCD display.
The response time for OLED is faster than normal LCD screens. Average 8 to 12 milliseconds response time is normal for an LCD compared to 0.01 milliseconds, a response time of an OLED. This means that OLED will be less subject to “blur”. Blur occurs when there is a rapid movement in programming such as sports. When the situation changes rapidly, the pixel is possible delay in response.
One problem that has limited the use of OLED technology is that the blue OLED’s life was short, but a new type of blue LED, the “PHOLED,” has a duration of 20,000 hours (20-25 years of normal use TV) . This was an important step forward in the effort to commercialize this technology for the HDTV market.
In theory, OLED displays can be produced more efficiently than LCD or plasma, which means that they should not be more expensive. The Sony XEL-1 sells for $ 2500, but you must remember that the first LCD and plasma displays have been much more expensive when they were introduced. If production costs can be cut, the set OLED HDTV should eventually be less expensive than comparable LCD September
OLED Performance Plus:
- Power Efficienct
- Very thin and light, 1 / 4 “or less
- Improving the brightness of the LCD
- Wide Viewing Angle (~ 160 degree viewing angle)
- An excellent contrast (> 1,000,000:1)
- After developing the production process should be inexpensive (the process is similar to ink-jet)
- Indicates Very Large are possible (> 100 in.)
- Response is better than LCD (good for fast-moving images like Sports)
If the OLED does not live up to its promise, will not be the first HDTV display to do so. I remember the surface-conduction electron-emitter display (SED TV)? Toshiba and Canon were ready to go into production, but the patent dispute with a company calLED Nano-Proprietary kill technology. Probably will not happen this time. The main obstacle will be the manufacturing process. If the unit can be produced economically competitive with LCD and Plasma, should be very interesting.
